20090121475 | DELIVERY PIPE FOR THE TRANSPORT OF SOLID MATERIAL, AND METHOD OF MAKING A DELIVERY PIPE - A delivery pipe for transporting solid material has a tubular body provided with a coupling collar on each end. The coupling collar includes a free space on its inner circumferential surface at the end distal to the end face. A sealing body is arranged in the free space. The invention also relates to a method for securing a coupling collar to an end of the tubular body of a delivery pipe by adhesion. The method is characterized in that a sealing body is arranged on an outer circumferential surface of the tubular body, and an adhesive is applied upon the outer circumferential surface between the sealing body and an end face. The coupling collar or the tubular body is then caused to rotate about the longitudinal pipe axis, and the coupling collar is pushed over the end of the tubular body, or vice versa. The sealing body is finally pushed into a free space of the coupling collar. | 05-14-2009 |
